Iridium Oxide Titanium Anode Tube for Wastewater Treatment

Iridium Oxide Titanium Anode Tube for Wastewater Treatment

In the electrochemical treatment of industrial wastewater, the structural design and catalytic activity of the anode tube jointly determine treatment efficiency and long-term operational stability. Our Iridium Oxide Titanium Anode Tube for Wastewater Treatment at Baoji City ShenAo Metal Materials Co., Ltd. is designed specifically for flow-through or immersion wastewater electrolytic treatment systems. It uses Grade 1 or Grade 2 pure titanium tube as the substrate, with a dense iridium oxide catalytic coating on the surface. The tubular structure, combined with a perforated design, provides ample flow channels for the wastewater and uniform current distribution. The iridium oxide coating maintains stable oxygen evolution electrocatalytic activity in strongly acidic, high-salinity, and complex wastewater compositions, achieving efficient degradation of organic pollutants through strong oxidizing species such as hydroxyl radicals generated at the anode surface. This anode tube is suitable for the electrochemical advanced oxidation treatment of refractory organic wastewaters from pharmaceutical, textile dyeing, chemical, and landfill leachate sources, serving as a reliable choice for ensuring treatment efficiency and long-cycle stable equipment operation.

This product is for B2B Industrial Use Only. Operators should follow relevant chemical safety protocols and wastewater treatment operation standards.

Technical Specifications

Why Choose Our Titanium Anodes?

• Exceptional Durability of Iridium Oxide Coating in Complex Wastewater
  Iridium oxide exhibits a very low corrosion rate among noble metal oxides at oxygen evolution potentials, attributable to the favorable thermodynamic stability of iridium oxide under strongly acidic and high potential conditions. When treating complex industrial wastewater containing organic acids, inorganic acids, and high salinity, the coating consistently maintains stable catalytic activity and structural integrity, making it suitable for long-cycle continuous electrochemical treatment systems and significantly reducing treatment efficiency decline and replacement frequency caused by coating degradation.
• Tubular Perforated Structure Enhancing Mass Transfer and Gas Venting
  The anode tube features a perforated design, allowing wastewater to flow evenly through the tube wall openings and creating favorable liquid exchange at the anode surface. This structure facilitates the rapid transfer of active species such as hydroxyl radicals generated at the anode surface into the bulk wastewater phase, while promptly venting gases produced by the oxygen evolution side reaction, preventing cell voltage rise and effective reaction area reduction caused by gas accumulation, and ensuring sustained stable treatment efficiency.
• Chemical Stability in High-Salinity and Strongly Acidic Wastewater
  Wastewater from pharmaceutical, chemical, and landfill leachate sources often contains high concentrations of salts, strong acids, or various organic solvents, posing severe chemical attack on electrode materials. The iridium oxide coating maintains a low corrosion rate in these extreme chemical environments, without significant passivation or dissolution due to drastic pH fluctuations or changes in salt concentration, making it suitable for long-term stable service under actual operating conditions with significant influent quality variations.
• Flexible Modular Assembly and Maintenance
  We can provide anode tube assemblies with standard flanged connections, supporting single or multiple tube series-parallel installation. The perforated tube structure features a high open area ratio, resisting clogging when treating wastewater containing suspended solids. When an anode tube reaches the end of its service life, it can be independently removed and replaced without replacing the entire assembly. We also offer used anode tube inspection and recoating services, helping you reduce long-term production line operation and maintenance costs.

Frequently Asked Questions

Q: What are the main differences between iridium oxide titanium anode tubes and plate anodes in wastewater treatment?
A: The primary advantage of tubular anode tubes lies in their flow-through structure and larger specific surface area. Wastewater can flow along both the inner and outer tube walls simultaneously, achieving higher mass transfer efficiency, making them particularly suitable for in-line or bypass online treatment systems. The tubular structure also offers better pressure resistance and sealing than plate anodes, facilitating integration into enclosed treatment units. Plate anodes are more suitable for open electrolytic cells and high-flow immersion treatment scenarios.

Q: How do I select the appropriate coating formulation based on wastewater composition?
A: It primarily depends on the acidity, salt composition, and organic pollutant type of the wastewater. Strongly acidic, high-salinity wastewater typically uses pure iridium oxide coatings to ensure chemical stability. Wastewater containing aromatic pollutants (such as phenols and dyes) can use iridium-tantalum composite coatings, balancing oxidation efficiency with service life. You can provide your wastewater quality report, and our engineers will recommend a matched coating solution and iridium loading.

Q: What should be noted when treating wastewater containing suspended solids with anode tubes?
A: It is recommended to install a pretreatment unit (such as a screen or sedimentation tank) at the inlet to control suspended solid particle size and concentration. During operation, periodically inspect the anode tube surface for solid deposit accumulation and arrange online or offline cleaning as needed. The perforated design of tubular anodes facilitates water flow, but a reasonable cleaning schedule should still be established based on water quality conditions.

Q: How should anode tubes be handled when the coating reaches the end of its service life?
A: The titanium tube substrate remains stable in the wastewater treatment environment. The old coating can be chemically stripped, and once the substrate passes inspection, it can be recoated to restore performance to new anode tube levels. We offer a full-service process including incoming inspection of used anode tubes, coating stripping, substrate treatment, and recoating.
